K.D. James (mbkdj at s-crim1.dl.ac.uk) gibbered:
} pH = pK' + log( (proton acceptor)/proton donor )
} pK' here is 6.68 at 25C (if I remember correctly- best to check
} this value!).
} Alternatively, you can find a ready-made table of quantities in most
} lab manuals.
Alternatively you can start with the two ingredients at the desired molar
concentration and use a pH meter......
